gdb: fix simulator build failures Following reports from me of build failures of the GDB simulator for the Blackfin architecture, Waldemar cooked a patch (0005-fix-sim-compile.patch) that removes the typedef of SIM_CPU, because there was a redefinition of this typedef for Blackfin. This was not causing an issue with recent compilers as redefining the same typedef is valid with recent compilers, but was causing build failures with gcc 4.4.x. However, by removing the common definition of SIM_CPU, this patch broke the build of the GDB simulator on other architectures, which did not had an architecture-specific redefinition of SIM_CPU (unlike Blackfin). The crux of the problem is in a commit from Mike Frysinger, that tries to refactor the SIM_CPU definition into a common one. Except that it leaves a redefinition of it for Blackfin. Removing this second definition however doesn't easily work, due to include ordering issues. The easiest solution is to simply revert the patch from Mike Frysinger. This allows to fix the build for all architectures and all compiler versions.

Subject: [PATCH] Revert "sim: unify SIM_CPU definition"
This reverts commit 20bca71d82598a015de0991196e45f0b5f7ead81.
This change causes a redefinition of SIM_CPU on the Blackfin
architecture, as it is defined in both the common sim/common/sim-base.h
and the architecture specific sim/bfin/sim-main.h.
